Application filed December 26, 1919. Serial 1:5.347551.

7 Beit known that I, GEORGE KNOCK, a citizen of the United States, residing at Cleveland in the countyof Cuyahoga and State of hio, have invented a certain new,

and useful Improvement in Filters, of which the followin' is a full, clear, and exact de-' orwater therethroughand into the carbureter. A further object of the invention is .to provide a filter of this character from which the water and sediment, may be conveniently removed, with the filter in either a vertical or a horizontal position. I accomplish these objects in and through the construction and arrangementlof parts shown in the drawings forming a part hereof, wherein Fig. 1 represents a side elevation of such filter; Fig. 2 a sectional view corresponding to the line 22 of Fig. 1; and Fig. 3 a sectional view corresponding to the line 3-3 of Fig. 2.

' Describing the various parts herein by reference characters, 1 denotes a cylindrical casing the opposite ends whereof are shown as seated respectively each within an annular groove formed in the removable heads 2 and 3.- VVit-h the filter arranged as shown herein, the head 2 is the lower, and the head '3 is the upper, head. The head 2 is provided with a threaded aperture 4:, preferably at one side thereof, and with asecond threaded aperture 5, preferably at the opposite side thereof. The aperture 4 receives a connection 6 to which the supply pipe 7 may be secured in any desirable manner.

This pipe may lead from the vacuum tank to the carbureter in vehicles providedwith such vacuum systems; or it may be interposed between a pressure tank and the carbureter, according to the equipment of the particular vehicle to which the filter is applied. Threaded into the aperture 5 is a drain connection 8 having a petcock 9 provided with the usual operating handle 10.

Mounted within the lower end of the casing 1 is a screen 11, of wire gauze, said Screen being carried by a ring 12 adapted FI TER:-

tOengage. the head2, preferablyjust outside j the apertures 4 and 5. Abovethe screen 11, there is provided a screen-13, preferably of the same mesh as. the screen 11 and carried by a ring l i projecting upwardly from the peripheralportion thereof. Above the ring 5 14 isa-spacing ring 14:. In the upper end of the casing l-there is shown a fine-mesh screen 15 supported at its -periphery-by a ring '16which is adaptedtoengagethe head- 3: The head 3 isshown aS provided with a v threaded aperture lTadapted to receive theconnection 18 forthe pipe-19-which leads to-the carbureter." I The. space-between the screens ll and 13,,will'b'e filled with granu V V latedmaterial 20,preferably'charcoal. In practice, the screen 15.:will beof about ;140160-fmesh f whilethe screens 11 and 13 will be of about 60'mesh. By the use of afilter such as shown and described herein, any water which may enter the chamber 21 beneath the screen 11 will be prevented from passing through the filter.

by the screen 15,]the latter screen, however,

permitting the passage of the gasoline; Also the major portion of any sediment which may be in the gasoline will be collected beneath the screen '11. The screens 11 and 13 serve also to support the filter mass 20, while the final screen 15 willposi tively prevent any water from passing to the pipe 19.

The, location of the aperture 5 and the drain outlet 8 enables water and sediment accumulating inthe chamber 21 to be re-' I moved with the filterv in a vertical or a horizontal position, it being necessary only to'see that'the aperture 5and its drain connection are at the bottom of the filterwhen it is employed in the latter position. The

filtering material 20 will arrest and retain any sediment that may pass through the. I

screen 11. By opening the petcock, the gasoline supplied through the pipe 7 will'serve to flush out any sediment in the, chamber between the head 2 and the screen 11. Having thus described my invention, what I claim is 1. A gasoline filter comprising a casing havingrat one end thereof a supply connection and a drain connection andat the other end an outlet connection, a screen extendmg ber, a second screeneextendin across said I casing and spaced from the first mentioned screen, filtering material in said casingbetween said screens, and a water-excluding screen of fine mesh wire within the casing of said heads having a supply connection and a drain connection located adjacent to the casing wall, and the other head having an outlet connection, a ring adapted to fit within the casing wall and to bear against the first-mentioned head, a screen supported by said ring and forming with said ring and the adjacent head a chamber communicating with the inlet and drain connections, a sec ond ring within said casing, a screen supported by the second ring, filtering material within said casing and interposed between said screens, a ring interposed between the outlet end of the casing and the second screen, and a water-excluding fine-mesh wire screen supported by the last mentioned ring and interposed between the second head and the second screen. 7

8. A gasoline filter comprising a casing and heads therefor and provided with a supply connection and a drain connection at one end thereof, the drain connection being located adjacent to the casmg wall, a screen vextending across said casing and forming with one of said heads a collecting chamber withwhich the said connections communi cate, a second screen extending across said casing and spaced from the first mentioned screen, filtering material in said casing between said screens, a water-excluding screen of fine-mesh Wire Within the casing at the opposite side of the filtering material from the first screen, a head beyond the third screen, and an outlet connection beyond such In testimony whereof, I hereunto affix my I signature.
